Principles of Operation
The instrument cluster and panel illumination consists of dimmable and non-dimmable illumination components. The dimmable illumination is controlled by the instrument panel dimmer switch, which allows the brightness level of the backlights to be adjusted to the customer preferences. With the parking lamps ON, the instrument panel dimmer switch uses electronic circuitry to provide a variable pulse width modulated (PWM) output to the instrument panel and all applicable switches depending on the driver-controlled level of intensity. The headlamp switch backlighting consists of 2 constantly illuminated LED bulbs that are powered by separate circuits. Battery voltage is supplied to the first bulb when the ignition switch is in the RUN position. Battery voltage is supplied to the second bulb with the parking lamps ON. The non-dimmable illumination allows for full intensity dependant on the ignition switch position.

Inspection and Verification

1. Verify the customer concern.

1. Visually inspect for obvious signs of mechanical or electrical damage.

Normal Operation A variable pulse width modulated (PWM) voltage is supplied to the instrument cluster through circuit 29S-LA31 (OG/BU). The instrument cluster is grounded through circuit 91-GG14 (BK/OG).

Possible Causes
• circuit 29S-LA31 (OG/BU) open
• circuit 91-GG14 (BK/OG) open
• instrument cluster

PINPOINT TEST B: THE INSTRUMENT CLUSTER ILLUMINATION IS INOPERATIVE CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.

This is both a courtesy and safety issue on many high end vehicles. The light from the interior lights can cast enough light to get to front door and possibly show dangers in your path. And after first getting into you car and starting it, you can check the back seat for any unwanted hitchhikers. As for the 10 minute timer, I don't know if this can be adjusted. A Chiltons/Haynes repair manual for you car may have that answer, or, the Buick dealership shop foreman. Best of luck.

What lights are not working ? The instrument cluster illumination is inoperative or all the lights ,radio , heater control head, all the switches that would be back lighted.

The climate control panel illumination is inoperative , The passenger door lock control switch illumination is inoperative. Could need new dimmer switch , new instrument cluster. When installing a new instrument cluster, it is necessary to upload the module configuration to the scan tool. Following installation of the new instrument cluster, download the module configuration from the scan tool into the new instrument cluster. Refer to Section 418-01 .

Does the van have remote keyless entry (RKE) system ?
Interior Lighting System Description
Vehicles with the optional remote keyless entry (RKE) system have interior lighting controlled by the body control module (BCM).
This vehicle uses a delayed interior lighting system.
The system functions as follows:
• The dome lamps will illuminate when any door is opened.
• The dome lamps will remain on for 20 seconds after the last door is closed.
• The delay is canceled and the dome lamps will go out when the ignition switch is turned to the ON position.
• The illuminated entry function will not operate when the dome lamp defeat switch is in the OFF position.
• The interior lighting system is protected from battery rundown by the retained accessory power (RAP) system. The RAP system functions by shutting down interior lights after 10 minutes (when ignition is OFF).

Interior Lights Circuit Description
When the interior lamps circuits are closed/enabled, the courtesy lamp relay is activated by the two following coil circuits:
• CKT 690 (GRY/BLK) which is the courtesy lamp enable output of the body control module (BCM) driving the coil side of the relay.
• CKT 1732 (ORN) which is the coil output side of the relay going to the potential grounding switches/sources.
When the courtesy lamp relay is enabled, CKT 156 (WHT) (courtesy lamp output) is enabled by the closed contact at the relay and then grounded by CKT 750 (BLK) at G110.
Some of these circuits can also be activated with the headlamp and panel dimmer switch. When this happens, the coil output side of the inadvertent power relay is grounded to the body control module (BCM) via CKT 1393 (DK BLU)
CKT 40 (ORN) from the courtesy fuse drives both input sides of the inadvertent power relay. When the contact is pulled closed, CKT 1732 (ORN) is supplied power, thus driving any lamps/circuits attached that circuit and providing ground.
The body control module (BCM) also monitors the following four door inputs:
• CKT 49 (DK BLU) -- LH door jamb switch input
• CKT 54 (ORN) -- RH door jamb switch input
• CKT 775 (PNK) -- Side door jamb switch input
• CKT 656 (YEL) -- Rear door jamb switch input/liftgate strut switch input (depending on option content)
When the doors are closed, the body control module (BCM) is in a floating state of 0-2 volts. When the doors are opened, the courtesy lamp relay is activated, sending power to the courtesy lamps.
The headlamp and panel dimmer switch also activates the following interior courtesy lamps when the switch is placed in the PARK or HEADLAMP ON positions:
• RF power window switch
• RH power door lock switch
• LH power window switch
• LH power door lock switch
• LH outside rearview mirror control switch
• Rear radio control head
The dome lamps can be disabled by closing the dome lamp defeat switch located on the headlamp and panel dimmer switch.

You obviously burned out something inside. Many of these scopes require a proprietary style 12 volt plug with the correct polarity ---

My only suggestion would be to contact celestron and send it in for repair.

The interior lamps system consists of 2 main features. Illuminated entry and a battery saver feature that will turn the interior lights off after 20 minutes if they are left On with all doors closed and the ignition Off. The body control module (BCM) controls both of these functions. Battery power is supplied by the BCM through CKT 1732 to the following lamps:
• The dome lamp
• The map lamps
• The rear reading lamps
• The rear dome lamp
• The cargo lamp
• The glove compartment lamp
• The courtesy lamps
• The sunshade lamps
The BCM also controls the ground circuit side of the dome lamp and reading lamps for illuminated entry. The dome lamp and reading lamp will remain on for 20 seconds after the ignition key is removed and the last door is closed. In addition, if the vehicle is equipped with remote keyless entry (RKE), the dome and reading lamps will turn On and stay on for 20 seconds after an UNLOCK signal is received from the keyless entry transmitter.
The reading lamps, dome lamp and map lamps can be turned On at any time by moving the appropriate switch to the On position.
The rear dome lamp is fed battery voltage through CKT 1732 from the BCM, through the liftgate ajar switch, and is grounded through CKT 650 to the rear ground splice pack. The rear dome lamp will turn on when the liftgate is opened. The cargo lamp is fed battery voltage through CKT 1732 from the BCM, through CKT 744 and grounded through the decklid ajar switch.
The courtesy lamps are fed battery power through CKT 1732 and are grounded through CKT 745-- left front, CKT 747--left rear, CKT 748--right rear, CKT 746--right front. These circuits will ground through the door jamb switches. The courtesy lamp will be illuminated when the affected door is opened. For example, when the right rear door is opened, the right rear door courtesy lamp will turn on.

Not a fuse problem , if the BCM had blown fuse other thing's wouldn't be working as well . . Probably wiring or BCM . Using factory diagnostic,s instead of guessing as to what the problem is , is the proper way .

Interior Lamps Diagnosis
Symptom
Procedure
Important: Before proceeding with these diagnostics, check for DTCs. If DTCs are present, complete the associated diagnostics. If the condition still exists, return to this chart.
All of the interior lamps are inoperative when any door is opened.
Chart 1
The dome lamp is inoperative in the ON position, but OK in the door position. The map lamps operate normally.
The dome lamp switch is faulty. Replace the dome lamp switch.
The dome lamp is inoperative in the DOOR position, but is OK in the ON position.
Chart 2
The dome lamp is inoperative in any position and both reading lamps are inoperative.
Disconnect the dome lamp connector (BLK 3-way).
Check for voltage at terminal "C" CKT 1732 ORN wire.
If OK, the dome/map lamp is faulty. If no voltage is present, there is an OPEN in CKT 1732.
Either the right or the left sunshade mirror lamp is inoperative.
Chart 3
Either the right or the left rear reading lamp is inoperative in the ON or the DOOR position.
Chart 4
The rear reading lamp is inoperative in the ON or the DOOR position.
